Alot of people had this question why ML after getting betray by the family decided to marry their daughter. It's simple when media will be there who wants to put their reputation in sewage??
As per the og, The FL refused to marry him and she practically announced she doesn't want to marry in her life. The parents asked her to marry him as the society will make their life hell. She was adamant in her decision. Later on the FL father asked the grandpa to accept her daughter as DIL and let her wed with him after his daughter run away. They were helpless.
The ML agrees only to accept her and marry to save their reputation. While she was forced to accept him. She was accepted by all, even the Mother in law and Her husband. Yes, she was asked to stay away from her husband and live in the storeroom. And she follows it with whole heartedly till 100 episodes. However, The FL accepted that her family did wrong but what was the most wrong thing was her sister run away with his brother who lied to her that he is the boss and you are his assistant. He also lied to her sister about some other stuff.
ML never liked The Bhagodi sister, he later accepted her as his sister btw. The Bhagodi sister loved ML bro not the ML. The ML loves FL and we will see how she will prove her innocence and still doesn't want to accept this marriage but will be asked to accept.
